Hello - We have two Quad QSA-30As that won't boot. These two machines haven't been run since October (they are backup machines), and there were some heavy lightning storms that month. We think both mother boards may have been zapped. We replaced

Hi Team, We using one of tanatalum capacitor ( vishay) for many models , in this we facing mis-alignment & throwoff issues after post reflow stage. After my analysis,my suspection is that due to one side part termination design ( square cut) issues

Hi Steve, Thanks. This from the trusted supplier. HASL finished PCB. Even PCB supplier is using the water wash flux for fabrication. Its almost eliminated with N2 environment. And we had got a expert view from Dr. Lee of Indium on the issue st

I'm wrestling with the infamous adjustable torque drivers on the production floor. Despite a procedure that clearly forbids it, we still have the occasional know-it-all that will just crank the knob until the desired setting is visible in the windo

You can buy an awful lot of PCB's with that budget. Having done multilayer at home for RF I would not recommend it. It took us 7 years to get a workable but I would not say reliable process running. 4 layer boards, plated through, green and silk scr

Hello, I've done it before in Excel and it is a very simple concept. Inputs are board size, numbers of SMT and TH process sides, number of SMT and TH placements per side, boards per panel and quantity of boards to be produced. Output will be calcul

Grandpa, You got it - Identifying the bottleneck operation is the key. The secret is to design a tool can predict accurately where this bottleneck is. In your formula you can use machine process time, PCB transportation time, part trim time, part in
